Bulletin

Solar activity was very low in the past 24 hours. No C-class flares, no Earth-directed CMEs were observed. NOAA AR 2605 (Catania 52) is decaying, while old active region NOAA 2602 is rounding the northeast limb. There are 2 stable filaments on the visible side of the solar disk. Solar proton flux intensity is expected to lie within the background levels. Quiet flaring conditions are expected to continue, with a small chance of an isolated B-class flare. Solar wind speed decreased from about 440 km/s to its current values near 390 km/s. Total Interplanetary Magnetic Field (IMF) strength fluctuated between 6 nT and 8 nT, while Bz fluctuated between +1 nT and -6.5 nT, and was mostly negative. As the result the geomagnetic conditions have been slightly disturbed in the past 24 hours, (K Dourbes between 2 and 4; NOAA Kp between 2 and 4). The geomagnetic environment is expected to continue at the slightly disturbed levels, minor geomagnetic storm (Kp=4, Dst = 60) can be expected today.

Today's estimated international sunspot number (ISN): 031, based on 21 stations.
